and the guide pressure with which the yarn is deposited on the package.

In the accompanying drawings, Figure 1 is aside vicw of a winding machine with my invcntion applied, showing the relation of itscomponcnt members when thrpackage wound has attained a material diameter. Fig. 2 shows a side elevation of my invention. Fig 3 shows a plan view. Fig. 4 shows my invention as applied to a machine of different type from that shown in Fig. 1.

machine of usual structure. in which the traversing thread guide is rcciprocated on a swinging frame whereby it is maintained in contact with the surface of the package wound at all times during the winding, through tiic action of properly disposed weights.

My invention is a device which, connected with the thread guide or other machine part having movement clfcctc'd or affected by the increasing diameter of the pzu'kngc wound, acts concurrently to hoth press the zuidc against thc package and tension the yarn, and to automatically vary the degree of both pressure and tension.

\Yhilo [ht-tension device may be of any suitable char-attend prefer the construction shown, in which a suitable bracket supports two opposed tension memlicrs formed with alternating parallel bars, one membv-r 1 fixed and the other d hinged to swing toward the tin-d member. The movable member is operated by moans hereinafter dcscribcd to press upon the thread as it passcs between the two members, crossing their bars, to sinuate its course and thcrcbyiapply tension.

My control device comprises the arm a, hinged to some fixed portion of the machine, as the tension bracket 1;, and a second arm 0 which is connected with the movable tcnsion member d "by the rod e, which rod i formcd at one end with an eye that engages the arm of the movable tension member, and at the other and,

with an eye which engages the lug g of the arm 1'. The firm a is conncctcd with the swinging frame it, in which 71-: thread guide reciprocates, my the rod 2' and adjustable connection j. On tho arm a is a wcight .t, and on th arm 0 is a weight I, each weight adjustablc in position on its arm. Rcicrring to the drawings, the tend- -[y invention is shown in Figs. 1 to 3 applied to a r ency of the weight It is to turn the arm a clockwise, and act through the rod i and adjustable connection 9' to swing the frame in and press the reciprocating guide m toward the winding spindle. The action of the weight I is to turn the arm 0 in the reverse direction and, through the rod e, press the movable tension member upon the yarn.

I lt is obvious that the relative positions of the arms a and 0 will vary with the position of 'the swinging frame h. When the Winding of a package is commenced, the guide or bears directly on the tube or on the winding spindle 1t, and the arms a and c are in a guide or is shifted with the increasing diameter of-the' package wound, the arms and 0 are concurrently turned up, decreasing the leverage with whirh their respective weights is and I act, and diminishing their effect on the guide pressure arid yarn tension.

The maximum admissible degree oi'tension or pressure for a given yarn is adjusted by varying the location of the weights Z: and l on their respective arms as required.

Referring more particularly to the details of structure employed, the arm a is mounted on a stud or screw pin 0 and is formed with notches or indentations p along one edge, which indentations are preferably numbered for ready reference in making adjustments. The weight k may be of any desired form, channeled to receive the arm a and secured thereto by the spring q. This spring q is formed with a projection ,r'that engages the indentations p to secure the weight Ii: in desired position. The weight 1 is similarly secured to the arm 0.

The arm 0 is mounted directly on the end of the rod 1' and thereby hinged to the arm a, for the end of the rod 1' is formed at right angles to its body, to engage the arm [1 and connect it with the swinging frame It.

' This right angled end 3 of the rod 't' is made of sufiicient place, as well as to act on the tensions; and the rod t" serves as a mounting for the arm 0 as well as ior a connection between the swinging frame h and the arm a.

The adjustable connection j is preferably a piece of wire or rod of L-form, one arm of which is adapted to engage one oi the holes-t in the swinging frame it and the other arm internally screw threaded to receive the screw threaded end of thc'rod t'.

a on which the frame it swings, there will be imported to the arms a and c rninimum movement during the winding of 9. package. ll, on the eontrmy, a maxi: mum degree of variation demanded, connection would be made vith the lowermost of the holes 17,

- which being farlhcst removed iron the zixis of turning of the frame 1:, would cause the the arms a and c.

It-is obvious that other'iorrns of structure can be made embodying the some inventional principles. I have shown the parts made from steel stanlpings, but it is obvious that other'mntcrials could b employed, as castings; that the weights is and Z could be secured in position by set screws and that other modes of attachmcnt and of connection for 'the device itself might be employed.

greatest movement of I have shown my invention preferably connected- With a Winding machine in which the guide swings to -and from the winding spindle, but in Fig. 4 is shown means for employing the same device with amachine in which the guide moves to and from the winding spindle with rectilinear movement. The device is eqnnllv adaptable to a machine in which the converse structure is employed-wher the guide 'is stationary and the package moves, relative to the guide.

Therefore, witbout'iimiting myself to {be precise structure disclosed, E claim:

1. The coni'olnstion with winding splndle and reclproccting guide, of co-scting swinging arms, and .velgllts on sold arms arranged to rt the separation of sold windlng spindle and guide with a decreasing resistance. f

2. The conxblnc tlou with a-tenslon devlee,,a reciprocatlng ,guldc, gnd a spindle on'which the package is wound, of

connected pivoted arms, Weights on said Firms, and connections between the arms and the guide and tension device whereby the weights cause pressure between the guide and the paqkage wound and actlon'of the tension.

device, said pnrrs arrangefl to secure :1 varying degree of pressure and tenslon with the varying diameter of the package.

3. The combination of :1 yarn controlling device with a mccnine having a moving member-and a tension device, said controlling device having two separate co ncling plvoted arms, weights on said arms, means for connecting one other arm wlth the'moving machine member, whereby the relative pooitions oi the two arms shall be varied for the purpose GESCZHJSG.

4. The comblnation \vlth a Winding spindle, :1 reclproesilug guide and :1 tensiondevlce, of a device connecting the qulde with the tension devlce and comprlsln g an arm, a. weight on thenrm, conneetlons whereby a separation vof the guide and winding spindle causes the arm to be shlited to decrease tlzepressurc of the weight, a second arm hinged to the first, :1 welght on said secondl'nrm, and a connection between the latter and the tension device, substantially as described.

The combination with a tension device of a yarn controller having the arm I], weight 1;, pin 0, the arm o mounted on the are: 11, weight l, and the rod 1; formed at one end to constitute a bearlngfor the arm 0 and having a whereby the effects of said xveights are automatically varledf 7. The cornblnntlon-ln a yarn controller of an arm :2, having graduating notches p, a welgllt k slldahly inounted thereon, and a sprlng q to secure tbewelglst to the arm,
